It's official now: Calvin Johnson has retired. 

Although the news of his retirement broke a while back, the Detroit Lions made it official today when they sent out this tweet: 

 Johnson finishes his illustrious career with 731 receptions for 11,619 yards and 83 touchdowns while averaging 86.1 yards per game. He was a six-time Pro Bowler and made the 1st-Team All-Pro roster three times during his nine year career. 

Despite retiring at the relatively early age of 30, he holds several Detroit Lions and NFL receiving records. Some of those NFL records include: most receiving yards in a single season (1,964), most consecutive games with at least 100 receiving yards (8), and fastest to 10,000 NFL receiving yards (115 games). 

He's the Lions' franchise leader in most receiving touchdowns in a season (16), most receiving yards in a single regulation game (329), and most seasons with 10 or more receiving touchdowns (4), among others.
